Detailed description of the invention
For the technical scheme making those skilled in the art be more fully understood that in this utility model, below in conjunction with this reality
With the accompanying drawing in new embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that
Described embodiment is only a part of embodiment of the present utility model rather than whole embodiments.New based on this practicality
Embodiment in type, the every other enforcement that those of ordinary skill in the art are obtained under not making creative work premise
Example, all should belong to the scope of this utility model protection.
Refer to Fig. 1, the open a kind of air switch locking device of this utility model embodiment.Disclosed air switch
Base 100 and threaded fastener 200 is included with locking device.
Base 100 is made up of insulant, the most irregular triangular prism structure, as it is shown in figure 1, the bottom surface of base 100
For being attached to the front panel 410 of air switch 400.Base 100 is provided with bayonet socket 110 and screwed hole 120, bayonet socket 110 and spiral shell
Pit 120 intersects.In the application, the shape of bayonet socket 110 is suitable with the shape of the handle 420 of air switch 400 so that bayonet socket
110 can be located on the handle 420 of air switch 400.
Threaded fastener 200 coordinates with screwed hole 120, in threaded fastener 200 can extend bayonet socket 110 and air switch
Handle 420 end face of 400 offsets cooperation, to apply to make base 100 to fit the front panel 410 of air switch 400 to base 100
It is adjacent to power, and then whole base 100 is fastened on the front panel 410 of air switch 400, also allow for whole air and open
Close locking device to be fixed on the front panel 410 of air switch 400.This kind of situation, the portion that bayonet socket 110 contacts with handle 420
Position is equivalent to a fulcrum, along with the locking of threaded fastener 200 makes whole base 100 contact with handle 420 with bayonet socket 110
To be fulcrum rotate towards the direction being adjacent to front panel 410 at position, and then realize the fixing of whole locking device.
In air switch locking device disclosed in this utility model embodiment, by threaded fastener 200 and screwed hole
120 cooperations realize whole locking device and are fixed on the front panel 410 of air switch 400, now, and whole locking device and air
Switch 400 one entirety of formation, makes bayonet socket 110 and the common locked hand 420 of threaded fastener 200, it is impossible to air simultaneously
The handle 420 of switch 400 implements any operation, is therefore avoided that in circuit maintenance process, and carry out closing a floodgate behaviour by mistake to handle 420
Operate.Visible, air switch locking device disclosed in this utility model embodiment can solve air in circuit maintenance process
Switch is easier to the existing security hidden trouble that closes a floodgate.
In order to improve the safety of locking device further, stop other people operation to threaded fastener 200 further, excellent
Choosing, disclosed in this utility model embodiment, locking device can also include lockset 300.Lockset 300 is arranged on base 100,
For blocking screwed hole 120, and then it is avoided that other people pass through tool operation threaded fastener 200.
The kind of the lockset 300 that can realize closure screwed hole 120 has multiple.Referring again to Fig. 1, a kind of concrete enforcement
Mode is: lockset 300 includes lock body 310 and dead bolt 320.Lock body 310 is fixed on base 100, is the master of whole lockset 300
Body, dead bolt 320 is arranged on lock body 310, and can stretch relative to lock body 310.When lockset 300 is in locking state, dead bolt 320
Can stretch out relative to lock body 310, be in the position of closure screwed hole 120.When lockset 300 is in released state, dead bolt 320 can phase
Lock body 310 is bounced back, and then is in the position dodging screwed hole 120.Operator realizes the behaviour to lockset 300 by key
Make, and then realize dead bolt 320 and to the closure of screwed hole 120 or dodge.Concrete, lockset 300 can be drawer-lock.
It can be implemented closure at the entrance of screwed hole 120 by lockset 300, it is also possible at the middle part of screwed hole 120 to it
Closure.In order to improve safety, base 100 is internal can arrange receiving chamber, accommodates the chamber perforation by lock body 310 and screwed hole
120 connections, dead bolt 320 is positioned at receiving intracavity, and can extend in screwed hole 120 from perforation, finally realizes the envelope to screwed hole 120
Stifled.This kind of mode can realize dead bolt 320, at the middle part of screwed hole 120, it be implemented closure so that dead bolt 320 is in and is difficult to be broken
The middle part of bad screwed hole 120, can improve stability and the safety of locking.Preferably, lock body 310 is built in receiving chamber,
The lockhole of lock body 310 is positioned at the outside of base 100, say, that lock body 310 by from accommodate intracavity fixing by the way of realize with
The connection of base 100, it is to avoid lockset 300 is disassembled from outside.
In locking device disclosed in this utility model embodiment, screwed hole 120 can include the unthreaded hole section 121 accepted successively
And thread segment.Thread segment can be easy to threaded fasteners 200 and screwed hole near bayonet socket 110, this kind of structure of screwed hole 120
The connection of 120, and then improve both joint efficiencies.
Refer to Fig. 2, bayonet socket 110 is for passing for handle 420, and final handle 420 is at threaded fastener 200 and bayonet socket
The common effect of 110 is locked, and in order to improve locking effect, the edge of bayonet socket 110 can be jagged edge 111, zigzag
Edge 111 can increase the frictional force between bayonet socket 110 and handle 420.
Refer to Fig. 3, in the application, the head end of threaded fastener 200 can be most advanced and sophisticated 210, it is simple to the pressure to handle 420
Fasten.The tail end of threaded fastener 200 can arrange word opening or a cross open, it is simple to operator use screwdriver to grasp
Make coordinating of threaded fastener 200 and screwed hole 120.
Referring again to Fig. 1, disclosed in this utility model embodiment, the locking device of air switch can also include hook
500, hook 500 is arranged on base 100, is used for hanging warning sign.The layout of hook 500 can be more conveniently for operator
Member hang warning sign, do not have warning sign hang on handle 420 existing for the problem being easier to come off.Equally, hook
500 can adopt and are made from an insulative material.
Herein, what each preferred version only emphasis described is different from other scheme, if each preferred version
Do not conflict, can combination in any, the embodiment formed after combination is also within category disclosed in this specification, it is contemplated that
Text is succinct, and the embodiment with regard to no longer being formed combination individually describes herein.
The above is only detailed description of the invention of the present utility model, makes to skilled artisans appreciate that or realize this
Utility model.Multiple amendment to these embodiments will be apparent to one skilled in the art, herein institute
The General Principle of definition can realize in the case of without departing from spirit or scope of the present utility model in other embodiments.
Therefore, this utility model is not intended to be limited to the embodiments shown herein, and is to fit to former with disclosed herein
The widest scope that reason is consistent with features of novelty.
